At present,intravenous thrombolysis within 4.5 h is still the most effective method in treatment of acute ischemic stroke.For those who do not meet the criteria of intravenous thrombolytic therapy,do not have significant improvement after intravenous thrombolysis and even worse,endovascular interventional therapy is a safe alternative treatment method.Arterial mechanical thrombectomy devices can achieve rapid and complete recanalization and provide more treatment options for patients with acute ischemic stroke.This article reviews the related technical evolution and clinical trials of mechanical thrombectomy devices.

Objective To compare the characteristics of food and nutrition intake in type 2 diabetes mellitus (T2DM) patients with or without carotid atherosclerosis and analyze the relationship between diets/C-reactive protein (CRP) and carotid intima-media thickness (C-IMT). Methods Sixty patients with T2DM were enrolled and divided into two groups based on C-IMT: group A (C-IMT ＜ 1 mm, n=30) and group B (C-IMT≥1 mm, n=30). All subjects were investigated with questionnaires including 3-day food recall They all took somatometric measurement. Blood and urine samples were collected in all subjects to examine the levels of high sensitive-CRP,C-peptide, blood glucose, glycosylated hemoglobin, blood lipid, renal function, urine microalbumin, and other indicators. Results The intakes of vegetables, fruits, and aquatic products were significantly higher in group A than in group B ( P ＜ 0. 05 ). The intake of vitamin C in group A was significantly higher than that in group B ( P ＜0. 05 ). The levels of CRP in group B was significant higher than that in group A (P = 0. 000). Positive correlation was found between CRP level and C-IMT in T2DM patients ( r = 0. 36, P = 0. 004). Furthermore, CRP was negatively correlated with the intakes of vegetables and fruits ( r = - 0. 334, P = 0. 01 ), aquatic products ( r = -0. 315, P = 0. 016), and vitamin C ( r = - 0. 2786, P = 0. 038 ), respectively. The intake of fruits was negatively correlated with C-IMT (r, = -0. 33, P = 0. 01 ). Conclusions T2DM patients without carotid atherosclerosis intake more vegetables, fruits, aquatic products and vitamin C than those with atherosclerosis. Vegetables, fruits,sea foods and vitamin C may be the protective factors against atherosclerosis in T2DM patients. CRP is associated with the development of atherosclerosis in T2DM patients.

Objective To investigate the telomerase activity and abnormality of p16 gene in liver metastatic tumors of colorectal carcinoma. Methods Telomerase activity was detected by a non isotopic PCR based TRAP assay (Telomeric repeat amplification protocol) and the homozygous deletions of p16 gene was detected by a semiquantitative multiple PCR in tissue samples from 24 liver metastases of colorectal carcinoma. Results Telomerase activity were observed in 19 (79 2%) out of the 24 colorectal carcinoma patients. There was no correlation hetween the telomerase activity, the number of metastasis, differentiation, liver fibrosis and HBsAg status of the patients. Homozygous deletions of p16 gene were found in 9 out of 24 (37 5%) patients, and homozygous deletions of p16 gene was significantly correlated with telomerase activity.Conclusion The abnormality in telomerase activity and homozygous deletions of p16 gene may be important for elucidating in liver metastases of colorectal carcinoma.

BACKGROUND: The oxidation of low density lipoprotein (LDL) is a key influencing factor in the occurrence and development process of atherosclerosis. How is the merit of the method for the detection of the level of anti-serum oxidized LDL (ox-LDL) antibody on the evaluation of atherosclerotic plaque?OBJECTIVE: To study the method for the detection of serum anti-ox-LDL antibody in mice with apolipoprotein E (Apo-E) genetic defect to analyze the merits of serous level of anti-ox-LDL antibody on the evaluation of the area of atherosclerotic plaque in mice with Apo-E genetic defect.DESIGN: Single factor analysis of variance (a case-controlled study)SETTING: Laboratory of nutrition and metabolism diseases in a university.PARTICIPANTS: Mice with Apo-E genetic defect were grouped into positive group (series: C57B L/6J, n = 15), while normal mice were grouped into control group (series: C57BL/6J, n = 15).INTERVENTIONS: Mice of two groups were fed in separate cage on laminar flow shelf for free drinking and eating. The venous blood was drawn from the orbit of mice after 16 weeks for the separation of mice serum. The level of anti-ox-LDL antibody was detected by enzyme-linked immunosorbent assay (ELISA) in the separated serum from either mice with Apo-E genetic defect or normal mice. The area of atherosclerotic plaque was measured by image analysis after oil red O staining.MAIN OUTCOME MEASURES: ox-LDL level and atherosclerotic plaque area in mice with Apo-E genetic defect or normal mice.RESULTS: Anti-ox-LDL antibody level of mice with Apo-E genetic defect was[ (0. 079 ±0. 028)% ], which was significantly higher than [(0. 012± 0.001 )% ] of normal mice ( F= 10. 666, P ＜ 0.01 ). The area of atherosclerotic plaque of mice with Apo-E genetic defect was (26. 25 ± 9.20) %, which was also significantly higher than 0% of normal mice, and moreover, there was a significant correlation between these two factors ( r =0. 638, P ＜ 0.01).CONCLUSION: Serum level of anti-ox-LDL antibody in mice with Apo-E genetic defect is closely correlated with the area of atherosclerotic plaque,which is an important indicator for the generation of atherosclerosis in mice with Apo-E genetic defect.
